+* Simulator to develop on PC without embedded hardware
+* Tutorials, examples, themes for rapid development
+* Documentation and API references online
 
-There are two branches: master and beta. In beta you will find the newest features which are not released yet.
+## Porting
+In the most sime case you need 4 things:
+1. Call `lv_tick_inc(1)` in every millisecods in a Timer or Task
+2. Register a function which can **copy a pixel array** to an area of the screen.
+3. Register a function which can **read an input device**. (E.g. touch pad)
+4. Call `lv_task_handler()` periodically in every few milliseconds
+For more information visit https://littlevgl.com/porting
+Or check the [Porting tutorial](https://github.com/littlevgl/lv_examples/blob/master/lv_tutorial/0_porting/lv_tutorial_porting.c)
+ 
+## Project set-up
+1. **Clone** or [Download](https://littlevgl.com/download) the lvgl repository: `git clone  https://github.com/littlevgl/lvgl.git`
+2. **Create project** with your prefered IDE and add the *lvgl* folder
+3. Copy **lvgl/lv_conf_templ.h** as **lv_conf.h** next to the *lvgl* folder
+4. In the lv_conf.h delete the first `#if 0` and its `#endif`. Let the default configurations at first.
+5. In your *main.c*: #include "lvgl/lvgl.h"   
+6. In your *main function*:
+   * lvgl_init();
+   * tick, display and input device initialization (see above)
+7. To **test** create a label: `lv_obj_t * label = lv_label_create(lv_scr_act(), NULL);`  
+8. In the main *while(1)* call `lv_task_handler();` and make a few milliseconds delay (e.g. `my_delay_ms(5);`) 
+9. Compile the code and load it to your embedded hardware
 
+## PC Simulator
+If you don't have got an embedded hardware you can test the graphics library in a PC simulator. The simulator uses [SDL2](https://www.libsdl.org/) to emulate a display on your monitor and a touch pad with your mouse.
 
+There is a pre-configured PC project for **Eclipse CDT** in this repository: https://github.com/littlevgl/pc_simulator

+# Contributing to Littlev Graphics Library
+It's glad to see that you are interested in Contributing to LittlevGL! 
+
+In this guide you can learn how can you help to develop  LittlevGL.

+
+## Who can contribute?
+As graphical interfaces for embedded systems has an increasing relevance today you also might find important to work with a good graphics library. Now - independently from skills, programming level or any personal attributes - you can influence and help the development of Littlev Graphics Library with:
+* Report an issue
+* Suggest feature
+* Fix an issue
+* Implement a feature
+* Help with testing bugfixes and new features
+
+Please, take a look at [CODE_OF_CONDUCT](https://github.com/littlevgl/lvgl/blob/master/docs/CODE_OF_CONDUCT.md)
+
+There a few general rules:
+* We use [GitHub's issue tracker](https://github.com/littlevgl/lvgl/issues)
+* Be kind and respectful. Strating with "Hi" is always a good idea :)
+* If somebedy helped you give a feedback.
+* Always create an issue before creating a [Pull request](https://help.github.com/articles/about-pull-requests/) (maybe somebeody already working on this issue)
+* One issue should be about one topic. If you have other questions please open a new issue.
+* Tell your remarks in a structured way. Use paragraphs and the [Markdown](https://guides.github.com/features/mastering-markdown/) support of GitHub.
+* Be sure you are using the lates version (from `master` branch)
+
+## How to report a bug?
+If you found a **simple and straightforward bug** like:
+* misspelling (in comments function/variable names or grammatical issues in comments)
+* not handled error cases (negative array index, overflow etc)
+* anything else which can be fixed locally with a few lines of code
+* or defective documentation
+
+then tell
+* where you found the bug (which file/function/variable)
+* how can it cause problem
+* what is your suggeseted solution if you have 
+
+If you faced with **something more clomplex** like:
+* might be simple but you don't know its origin
+* affects a whole file, module or even the architecture
+* needs deeper discussion
+
+then please
+* tell what do you experience
+* tell what do you expect to happen
+* tell how to reproduce the issue 
+* provide a simlified code example (better if can be tested with copy-paste)
+* attache your lv_conf.h (if you feel it's important)
+* logs and long codes should be attached in a file (instead of copying into a comment)
+
+## How to suggest a feature?
+If you have a good and useful idea open issue to tell it! Please note the followings on suggesting new features:
+* What the new feature is about?
+* Why/Where/In which case is it useful/helpful/relevant?
+* Can you mention real life usecases/examples for the use this feature?
+* Can you help in implementing it?
+
+Your suggestion can have 4 possible outcomes:
+1. This feature is already exists. In this case you will learn how to achive your goal.
+2. You can simply realize it with the current functionality.
+3. Although it's a new feature but it would break LittlevGL's platform independent and/or resource minimalist nature.
+4. It's really a new feature which would be good to be in LittlevGL. Hurray! In a discussion we figure out the technical details andimplementation options. With the knowledge of how to do it somebody can implement the new feature.
+
+Keep in mind if you wouldn't like to do the implementation there is no guarantee that it will be ready in the new future. 
+However if you would like to force it, take a look at this page: [Feature request service](http://www.gl.littlev.hu/services#feature)
+
+## How to implement a feature?
+In [docs/TODO_MINOR.md](https://github.com/littlevgl/lvgl/blob/master/docs/TODO_MINOR.md) and [docs/TODO_PATCH.md](https://github.com/littlevgl/lvgl/blob/master/docs/TODO_PATCH.md) you can see some ideas which are waiting for somebody to realize them! If want to deal with a feature from this files, please start an issue and discusse the details.
+
+The new feature should be in a new branch.
+
+## Styling guide
+
+### File format
+Use [lv_misc/lv_templ.c](https://github.com/littlevgl/lvgl/blob/master/lv_misc/lv_templ.c) and [lv_misc/lv_templ.h](https://github.com/littlevgl/lvgl/blob/master/lv_misc/lv_templ.h)
+
+### Naming conventions
+* Words are sparated by '_'
+* In variable and function names use only lower case letters (e.g. *height_tmp*)
+* In enums and defines use only upper case letters (e.g. *e.g. MAX_LINE_NUM*)
+* Global names (API):
+  * starts with *lv*
+  * followed by module name: *btn*, *label*, *style* etc.
+  * followed by the action (for functions): *set*, *get*, *refr* etc.
+  * closed with the subject: *name*, *size*, *state* etc. 
+* Typedefs
+  * prefer `typedef struct` and `typedef enum` instead of  `struct name` and `enum name`
+  * always add a closing *..._t*
+* Abbreviations:
+  * Use abbreviations on public names only if they become longer then 32 characters 
+  * Use only very straightforward (e.g. pos: position) or well established (e.g. pr: press) abbreviatons 
+
+### Coding guide
+* Functions:
+  * Try to write function shorter then is 50 lines 
+  * Always shorter then 100 lines (except very straightforwards) 
+* Variables:
+  * One line, one declaration (BAD: char x, y;)
+  * Use `<stdint.h>` (*uint8_t*, *int32_t* etc)
+  * Declare variables when needed (not all at function start)
+  * Use the smallest required scope
+  * Variables in a file (outside functions) are always *static*
+  * Do not use global variables (use functions to set/get static variables)
+
+### Comments
+Before every function have a comment like this:
+
+```c
+/**
+ * Return with the screen of an object
+ * @param obj pointer to an object
+ * @return pointer to a screen
+ */
+lv_obj_t * lv_obj_get_scr(lv_obj_t * obj); 
+```
+
+Always use `/* Something */` format and NOT `//Something`
+
+Write readable code to avoid descriptive comments like: 
+`x++; /* Add 1 to x */`. 
+The code should show clearly what you are doing.
+
+You should write **why** have you done this: 
+`x++; /*Because of closing '\0' of the string */`
+
+Short "code summaries" of a few lines are accepted. E.g. `/*Calculate the new coordinates*/`
+
+In comments use \` \` when refering to a variable. E.g. ``/*Update the value of `x_act`*/``
+
+### Formatting
+Here is example to show bracket placing and using of white spaces:
+```c
+/**
+ * Set a new text for a label. Memory will be allocated to store the text by the label.
+ * @param label pointer to a label object
+ * @param text '\0' terminated character string. NULL to refresh with the current text.
+ */
+void lv_label_set_text(lv_obj_t * label, const char * text)
+{   /* Main bracket of functions in new line*/
+    
+    if(label == NULL) return; /*No bracket only if the command is inline with the if statement*/
+    
+    lv_obj_inv(label);
+    
+    lv_label_ext_t * ext = lv_obj_get_ext(label);
+
+    /*Comment before a section */
+    if(text == ext->txt || text == NULL) {  /*Bracket of statements start inline*/
+        lv_label_refr_text(label);
+        return;   
+    }
+    
+    ...
+}
+```
+
+Use 4 spaces indentation instead of tab.
